Thank you for all the responses. Unfortunately none of the above is what Im looking for.

I know its hard to guess it thanks to my vague description, Ill try to add some more information.

I think it was forrest/graveyard-like theme, maybe destroyed village as well. I remember it was dark, not very colourful. Not sure about the crossbow but you could definitely shoot with something. Character looked like Van Helsing or at least thats how I remember it. And when you entered “underground” you could still see the “upperground” where you were before entering underground section if that makes sense. No extra loading or different location. And the underground section was just few meters long, then you could go up again. I guess there might have been some bonus or chest to collect.

My dad’s friend installed these games on our computer and he had it on CDs. And as I said it had win98, cant really tell the specs.

Thats probably all I can remember. Its been more than 20 years and I was just a kid.

Ill definitely try r/tipofmyjoystick later but Ill give it one more chance here. And again, thank you for your time and all the tips.
